Specification of Letters Patent.

Patented June '1,' 1920.

Application led November 30, 1917. Serial No. 204,683.

To all whom t may concer/rt:

Be it known that I, PRESTON G. BERE- MAND, a citizen of the United`States of America, residing at Bay City, in the county of Bay and Stateof Michigan, have invented certain new and useful Improvements inSectional VVheel-Rims, of which the following is a specication.

This invention relates to an improvement in sectional wheel rims forpenumatic tires.

The primary object of the invention is to provide a rim constructionwhich may be quickly and easily disassembled for the removal of the tireand which, when .in use, will securely support the tire.. v

A further object of the invention is to provide a rim construction inwhich the assembling and disassembling of the parts may be effected witha minimum manipu- 'lation of the securing devices. I n

With the above and other objects in view, the present invention consistsin the combination and arrangement of parts hereinafter more fullydescribed, illustrated in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes maybe made in the form, size, proportion and minor 'details withoutdeparting from thejspirit, or sacrificing any offthe advantages fof theinvention.

In the drawings: f

Figure V1 is an elevation of the rim, a portion being broken away; y

Fig. 2 is a section taken transversely through the rim on the line x-zcof Fig. 1;

Fig. 3 is a section taken on the line jf/-y of Fig. 1;

Fig. 4 is a section of the tire retaining members showing the retainingbolt inl position by full lines, andV also showing (in dotted lines) thebolt swung down when removing the tire, or placing it in position;

Fig. 5 is a fragmentary view showing the locking meansin position; p Y yFig. 6 is a plan of the same;

Fig. 7 is a section of one of the rim sections; 1

Fig. 8 is a side elevation ofthe same;

Fig. 9 is an enlarged detail lof the retaining boltand head; p l

Fig. 10 is a side elevation of the same; and

Fig. 11 is asection showing the locking means in position on the rim.

Referring now to the drawings, the numeral 10 indicates the annularmember con- 'stituting a liXed rim, which is riveted or otherwisesecured to the V-shaped annular member 9 and -to which the spokes V11Vare secured. Vhile wire spokes have been illustrated as attached to thefixed rim 10, it will be understood that any type of spoke may be used,or my improved rim may be lused on a disk wheel to equal advantage. vTheXed rim and the devices carried by the same may be applied to a wheel ofany structure on which it may be desired to use the same.

At one edge of the fixed rim 10 is formed an upstanding annularcontinuous rib '12, and in the center and at the opposite edge of therim are the lupstanding lugs 13 and 14. A tire engaging section 15 isprovided which is substantially one-half the width of the Xed rim 10,and which is formed with a curved flange 16 disposed to engage the beadof the tire. section 15 is provided with the spaced lugs The under faceof this 17, which when the member 15 is locked in I position on thefixed rim 10, as illustrated in Figs. 2l and 3, it is held securely inposition between the upstanding rib 12 and the lugs 13 of the Xed lrim10, which will prevent transverse movement of these sections on thefixed rim 10.

A second tire engaging section 18 is provided, which is of.substantially the same i configuration as the `member 15, the samebeing provided with a curved flange 19 engaging the bead of the tire.The under face of the member 18 is also provided with a Y series ofspaced lugs 2O which are of the Vof whichY isenlarged as shown andprovided with the opening 26. After said bolt member is inserted in theopening inthe member 24, the pin member 27 is inserted or driven throughsuitable openings in the member 24 and through the opening in the head25a of the bolt 25 and it will therefore Vbe obvious that said'bolt isfree Vto swivel two ways within the member 24, the head 25a having agroove or ridge4 across the head 25"1 in order that the operator mayknow when the bolt is in position to swivel and drop kout of its seat.

The retaining bolt 25 is provided at its opposite end with the lugs 29and 30, the lug 29 being 'of larger diameter than the lug 30,

in order that it may ride on the face of the member 10 when assemblingor disassemblingthe rim,'these lugs are slightly dished as shown,andwhen in position are disposed oneach side of the lug members '17 ofthe member 15, said lugs being provided with seats'for same, and whichis simply to facilitate theholding Vof the` bolt in position when thesections are loose.' f Y In order that mud and'other foreign matter` maynot enter the openings through which the lugs must pass when the rim isassembled and disassembled, I provide the cover` plate 31 Ywhich can bewelded or suitablybolted to the tire retaining section 18,

the member 10 having its one face slightly grooved in order that themember 31 may fit into same and the member 10 thus present a smoothappearance, it is also provided with the. necessary openings v32 toallow for the insertion of av wrench on the head 24a when it isnecessary to remove the tire ortighten the retaining sections.

In assembling the rim, one edge of the tire is placed in position on thesection 15, the other edge in position on the member 18the retainingbolts are then placed in position in the seatsprovided in the'lugs 117ofthe section 15, the` lugs 20'and 20 are then placed so that theyregister with the openings between the Alugs14 von the vmember 10, andthe whole is forced onto the rim until the lugs 17 butt against thecontinuous .rim member 12. The members 15 and 18 on whichare containedthe tire are then rotated until the lugs 20 are behind the lugs 14, anda wrench is then applied to the squared head of the member 24 whichnaturally forces' the members 15V and-18 from each other (as shownin'Fig. 4) and against the rim member 12 and the lugs 14, the tire valvebeing free to move in the slot 40 `of the rimflO.

Inasmuch as the lugs 20% are slightly longer than the lugs 20 and ofwhich I-prefer to use six, the opening 23 is not concealed after thetire and tire retaining` section has been rotated and the operatorap-Vplies the wrench as desired. To accommof date the quick .detachabletires having plane side faces, I provide an eXtra-ring 39 which isclearly shown in Fig. 3 (dotted'lines).

The fixed rim lO'isralso provided with an opening 33 in which isdisposed toV operate the key member 34, said Vkey member being Vheldinposition by means Vof the housing 38 and the small pinmember 35 whichhas an annular flange member 35a which is disposed to butt against thepin, being held in this position by the Vcoil spring 36'vvhich is p0-sitioned thereon.

. The key as shown securely fits the space between the lugs 20 and thusprevents further rotation of the tire retainingsections with relation tothe fixed rim 1 0, and, when it is desired to remove a tire the operatorforces the pin 35 inwardly by the aid of a smallV pointed tool thusallowing the key to assume the position as clearly shown lin dottedlines in Fig. 5, said key having an enlarged shoulder 342L which` ofcourse, limits the distance the key may drop, the operator neXt loosensthe retaining bolt 25, the tire retaining sectionsv are then rotatedVuntil the lugs registerwith the openings be- -fore be obvious that Ihave perfected a simple and inexpensive rim which vcan be quickly andeasily assembled and which will owing to the means for posi-tivelyaffecting a lateral movement of the rim sections eliminate the generaltrouble resulting from tires rusting to the rim as is the case with therims now on the market. The inner and outer lugs 13 and 14 form anintervening annular groove and the lugs 14 which are arranged in spacedrelation provide a recessed outer flange corresponding to the recessedflange vshown in my prior copending application No. 185,460.
